Girls' Generation Taeyeon's photo from four years ago is generating buzz online.

Following an online post of Taeyeon's photo from four years ago and its comparison to a recent photo, many are amazed by how little she has aged over time.

"I'm jealous of her preserved beauty" and "She gets more beautiful by the day, month and year," were some notable comments about Taeyeon.

Girls' Generation, which Taeyeon is a member of, left for Japan on March 25 for their 2013 Girls' Generation Arena Tour.
